<!-- overview -->
<!--
Bootstrap tokens are used for establishing bidirectional trust between a node joining
the cluster and a master node, as described in [authenticating with bootstrap tokens](/docs/reference/access-authn-authz/bootstrap-tokens/).
-->

如[使用引导令牌进行身份验证](/zh/docs/reference/access-authn-authz/bootstrap-tokens/)所描述的，引导令牌用于在即将加入集群的节点和主节点间建立双向认证。

<!--
`kubeadm init` creates an initial token with a 24-hour TTL. The following commands allow you to manage
such a token and also to create and manage new ones.
-->

`kubeadm init` 创建了一个有效期为 24 小时的令牌，下面的命令允许你管理令牌，也可以创建和管理新的令牌。
